HYDRAULIC PRESS.

SPECIFICATION forming part of Letters Patent NO. 255,872, dated April 4%, 1882,

To all whom it may concern Be it known that I, CORNELIUS KIMPLEN, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Hydraulic Machinery, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation with some of the parts partly broken away; Fig. 2, arighthand end elevation; Fig. 3, a left-hand end elevation; Fig. 4, a cross-section at line 00 m of Fig.3; Fig. 5, a top or plan view of the frame for supporting the turn-table; Fig. 6, a vertical section across the turn-table and head of the supporting-frame broken off; and Fig. 7, a cross-section on line y y of Fig. 1, being in the main a plan view of the bed-plate.

The object of this invention is to construct a hydraulic press for compressing ground tanbark or other bulky articles; and its nature consists in the improved construction, combination, and operation of the parts hereinafter described andclaimed as new.

f, pinion; g, cogs on turn-table; h, racks; h, cross-heads; t, pinions operating the racks h,- t", shafts; j, bevel-wheels; k, bearings for the shafts i; l, pinions m, horizontal curved rack; n, anti -friction bearingwheels for the turntable; 0, cord; 19, weight for counterbalancing the bark-cylinder pistons.

The base-plate A is located above the base H and supported upon suitable masonry for sustaining the parts in position. The hydraulic c5 linders E, l, and J, as shown, are located be-; low the plate A, and the cylinders I J are SUD- ported therefrom; but they may have additional supports, it required. The pressure-cyh inders E are supported upon the plate F and base H, and I make three of them, for the reason that it is less dit'ficult to construct them and much easier to repair them than would.

be the case with a single cylin ler of equal capacity. A plunger connectedwith the cap E is fitted to each of these cylinders, andthe water is admitted beneath the plungers or pistons from a single source, so that they will operate equally. The cap E is a strong cap designed to receive the pressure of all three of the pressure-cylinders E.

By the right side of the press I locate a steam-engine, M, which is provided with an ordinary piston, guided by the'plates N, and connected with the main shaft 0 by the usual pitman, O, and crank. It is also provided with an ordinarysteam-chest,L,the valves of which frame T and carries the two pinionsR S. The

pinion It drives the large gear-wheels U U, which operate the front and rear pumps K by cranks attached to their shafts on the pitmen K. The pistons or plungers of these pumps are guided by the guides N N. The

pinion S drives the large wheel V, which,

through its shaft V and crank and pitman,

operates the middle pump, the positions of the pumps being shown in Fig. 7..

The pumps K are all connected by suitable pipes or tubing with the changeblock, and the water is discharged into a common space. The

change-block W is provided with valves, by whichthe water can be directed into the cylinders E, I, or J, as may be desired, one valve admitting the water into all three of the cylinders E, while the cylinders I and Jhave separate valves. These valves are so arranged that the attendant changes the direction or force of the water as the work progresses to the desired points. I have not shown the change-block in detail, for the reason that it is a common device, well understood'by those familiar with the operations of hydraulic machinery. In the forms shown the change-block is to be worked by hand, and is arranged near the engine, so that the same person can attend to both.

The valves, if desired, may be connected with the pumping machinery, so as to shift automatically at stated periods; but in pressing bark the operations are liable to be somewhat irregular, and 1 have not therefore shown it so operated. The fountain from which the pumps take their water is located beneath the pumps at a point sufficientlylow for the waste water or overflow to return back into it, and the apparatus will be provided with one or more safety-valves, to prevent undue strain or breakage.

' The bark-cylinders X are made of a size to be sufficient in capacity to hold loosely the desired quantity of bark. There are three of them, and they are arranged as shown in Fig. 4, and are supported upon the turn-table. (Shown in plan in said figure.) They are attached to the turn-table and to the upper plate, and surrounded by a cylinder or casing, A.

' The plungers Y,vwhich operate from below, are made to fit tile bark-cylinders, and at their lower ends they are provided with the crossheads h, to which the racks h are attached, and they are counterbalanced by a' weight, 1), on the cord 0, Fig. 1, which cord winds upon the shaft i, and when not driven by the bydraulic press they are operated by the pinions i, which gear in the racks h. Each plungerY is provided with two racksone on each side. The pinions "L are operated by the bevel-wheels j, attached to the same shafts, which shafts are supported upon the turn-table by the bearings k.

One of each pair of shafts a" is provided with a pinion, l, which, through its bevel-wheel j, operates the other shaft of the pair, so that the movements of each pair are always in unison. The pinions l are operated by the curved rack m, Figs. 4 and 5, which occupies onethird of the circuit traversed by the turn-table, and is permanently attached to the cap or frame Z. The turn-table revolves around one of the rods B, and is supported by the antifriction wheels n, located in the cap or'frame Z, which wheels are provided with flanges to keep the turn-table in lateral position. The turn-table has its periphery or rim provided with cogs g, which engage with the pinionf, attached to the shaft 6, which has upon its lower end a bevel-wheel engaging with the bevel-wheel d on the shaft 1).

The pinion I) is operated by a rack, to, which is attached to or forms a part of the. stem of the piston or plunger operating in the hydraulic cylinder I. The piston J of the cylinder J is omitted in Fig. l of the drawings, in order that this gearing might not beobscured, as it stands immediatelyiu front thereof. The office of the piston J is to give the bark-plungers Y their final elevation for discharging the compressed bale. It will be understood that the parts are made of iron, and that all of the parts connected with the hydraulic press or with the pumps are to be strongly made.'

The operation of the pumping devices will be readily understood from the description. The operation of compressing bark is as follows: The bark is placed in the cylinder X, which hasits piston atthelow est point. \Vhen filled, water from the change-block W is turned into the cylinder I, which raises its piston and carries the rack no upward. This rack is so geared with the intermediate gearing that its complete movement gives the turn-table a one-third turn. This turn carries the cylinder with its depressed piston around over the cap E. l and the curved rack m, carries the next plunger in rear of the one just filled down to its lowest point hy means of the pinions t' and racks It. This one-third traverse of the turntable clears the pinion Zfrom the rackm, so that its motion may be reversed by the press without interfering with anything; but in this position the succeeding cylinder is ready to be filled, while the advance cylinder is ready for the press. By shifting the change-block the water is let out of the cylinder I and is shifted to the cylinders E, which raises the cap E and forces the bark-plunger upward, so as to give the contained bark or other material the required pressure against the cap or head-block G. The water is then discharged from the cylinders E, so that the cap E will descend. The water is then applied to the cylinder I, which again gives the turn-table a one-third move-' The same movement, through the pinion IIO ment, which movement advances the second cylinder over the hydraulic press, lowers the plunger for the receiving-cylinder, and brings the one pressed over the cylinder J. Water is then admitted to the-cylinders E and J, the cylinders E pressing the bark as before, while the cylinder J raises the plunger to the highest position shown, (the three positions named being respectively shown in Fig. 3,) which discharges thecompressed bark upon the top plate of the bark-cylinder casing, ready to be rolled off ,or otherwise disposed of. From this point the operation is continuousthat is, while the attendant is filling the first cylinder the bark in the second is being compressed and discharged from the third.

The cap or plunger may be arranged with two or a greater number of pistons operating do not limit the use of my other improvements to a machine having its press-cylinder divided, and the bark-cylinders may be square in cross section or of other angular form to produce an angular bale.

It will be seen that the piston J stands at its-lowest elevation, as shown in Fig. 3, so as to take the plungers Yin the position at which they are left by the press, so that all of the travel of the piston J is from that point upward, and as each bark-cylinder is provided with its own piston or plunger Y, the dischargin g-piston J does not enter the bark-cylinders. Therefore there is no time lost in retracting the discharging-piston, as the turn-table can be moved as soon as the cake or bale is thrown out, and the movement of the turn-table lowers the piston Y. t

It is also evident that more than three cylinders can be placed on the turn-table and all be operated by the described devices, for it makes no difference how far a cylinder travels after its plunger is at the lowest point; but when cylinders are added and the turn-table increased in diameter the length of the rack m. will not be increased, so that in that event its length will not be equal to one-third of the distance around.

What I claim as new, and desire to secure by Letters Patent, is-- l 1. In a hydraulic press, the combination of two or more bark-receiving cylinders with a cap carrying two or more pistons or plungers operating within the cylinders, and a pressure cap or plate located at the discharge end of the cylinders and coacting with each of the latter, substantially as and for the purpose described.

2. The hydraulic cylinder I, having a rack, a, on the piston-stem, in combination with the pinion b, and gears d, e, and f for operating the turn-table, substantially as specified.

3. The pinion l, in combination with the,

gers Y, with the hydraulic press E E and hydraulic cylinders I and J, said members being arranged for operation substantially. as and for the purpose described.

7. The combination of the pumps K, press E E, and hydraulic cylinders I J with the cylinders X and plungers Y, constructed and operating substantially as specified. 8. The discharging-piston J and cylinder J, in combination with a cylinder, X, having a piston or plunger, Y, substantially as and for the purpose specified.
